The day all the religious wackjobs think the world will end, which is today. This day also occured a century ago,, but I don't think anyone made as much of a big deal as they did today.
A century ago: ''It's 6/6/06. Oh well. Back to shucking corn.''
Today'' It's 6/6/06! AHHH RUN THE END IS NEAR! WERE ALL GONNA DIE!!
The date when all the stupid preppies and tv zombies thought it was going to be the end of the world because of the similarity of the date with the mark of the beast, 666. For everyone that thought that, the bible states that no one but God knows when the world will end, so get your facts right. Oh and there was also a crappy movie about it.
Middle School Preppie: AHH! It's 6/6/06 and we're all gonna die!!!!!!
Educated Person: Idiot no one knows when the world is going to end, the bible doesn't say anything about the number of the date.
Middle School Preppy: Yeah but still it's 666 AHHHHHHHH!
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
